 ## How to run?
 1. Install docker on your machine
-2. Then run the docker-compose file and make sure that port ```4000``` and ```3306``` are not in use.
+2. Then run the docker-compose file with ```docker compose up -d``` and make sure that ports ```4000```, ```4001``` and ```3306``` are not in use. Also make sure that you are in the root directory, ```login-page```.
 3. Then enter the mysql container (exec) with the credentials that you can see in the ```docker-compose.yml``` file and in the ```.env``` file.
 4. Then login with the root user with ```mysql -u root -p```, after that enter the password from the ```docker-compose.yml``` file or the ```.env``` file.
 5. Then type ```use login_page;```
 6. Then create a table with the following scheme (extract from scheme.sql):

--- Mock data for users
-INSERT INTO users (username, first_name, last_name, email, password)
